Today, I had a volleyball game, and we were down by 13 points. I looked up at the crowd, and my mom was shaking her head in disappointment. When it was my turn to serve, I aced them, and tied the score. When I looked up she was gone. She'd left. When I got home, I heard how I sucked for an hour. FML

I hate parents like this. I played sports in high school and you'd see parents screaming at their kids for not performing "good enough." Sometimes it would get so bad that the coaches would have to step in.

Reminds me of the time my mom came to one of my senior soccer games and I scored the only goal of my whole soccer career and after the game I went up to her and asked "did you see my goal?!" and she said no :p so I kind of know you how feel and I'm sorry :( but at least everyone who stayed knows what you did:)

No, but they're right. Unless there's a different set of rules for a different kind of volleyball game; but you can't tie the score with one ace when you've got a 13 point difference. And even with an ace serve it's still just 1 point gained, not 3. At least, like I said, in the volleyball that I know and grew up with. So this fml has got me completely confused as to what the OP meant. Did they mean that they gained 13 points in a row, or their team caught up the last 12 and then tied it with their ace serve?
Either way, that's a crappy mother to just a) walk out on the game and b) bitch about it later instead of comforting their kid.
